Liver injury: What you need to know

Area of Science:

• Trauma Surgery
• Hepatobiliary Surgery
• Surgical Anatomy

Background:

• Liver injuries are common abdominal solid organ injuries.
• Grades I-III injuries are most frequent, while grades IV-V represent 12-20% of cases.
• Nonoperative management (NOM) is successful in 85-90% of hemodynamically stable blunt liver injuries.

Purpose of the Study:

• To review diagnostic, resuscitation, and triage considerations for liver trauma.
• To discuss limitations and complications of NOM and angioembolization.
• To present operative strategies for severe liver injuries.

Main Methods:

• Review of critical surgical anatomy and grading systems for liver trauma.
• Evaluation of diagnostic and resuscitation protocols.
• Analysis of nonoperative management, angioembolization, and surgical techniques for severe injuries.

Main Results:

• NOM has decreased overall mortality for blunt liver injury.
• Advances have not significantly reduced morbidity/mortality for grades IV-V injuries.
• Angioembolization is effective but carries risks like hepatic necrosis and sepsis.

Conclusions:

• NOM is the standard for stable blunt liver injuries.
• Severe liver injuries (grades IV-V) require specialized operative management.
• The "6 Ps" strategy is proposed for surgical hemorrhage control in severe liver trauma.
